The widths of the two frames are approximately 0.0709 inches for Frame A and 0.0632 inches for Frame B.
Let's denote the length and width of Frame A as
respectively, and similarly
for Frame B.
The area
of a rectangle is given by the formula

For Frame A:
![\[ A_A = L_A * W_A \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/zx47fgly2b43bw0540t35x5scua5awtela.png)
For Frame B:
![\[ A_B = L_B * W_B \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/xrr0ltulw47pxlrpgiuejjqawsq4jv1wrt.png)
Given that both frames have the same area of 45 square inches:
![\[ A_A = A_B = 45 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/wl11gy4yb3yz5weureb5tlnr8uksbaqrlh.png)
You mentioned the length of Frame A
is 634 inches, and the length of Frame B
is 712 inches.
We can set up a system of equations to solve for the widths
:
![\[ L_A * W_A = 45 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/dm8wx5659anyq4h7sqsrf7198unmclzedi.png)
![\[ L_B * W_B = 45 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/z1ct1do8vrg3l14s7odujpkbvvuh52tw0l.png)
Substitute the given lengths:
![\[ 634 * W_A = 45 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/qva09nnl2566gog2id3gr4b5elm2a9x2ok.png)
![\[ 712 * W_B = 45 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/ef3usncqlzy7isccbl7gfvhhx3u8c0y9xx.png)
Now, solve for

![\[ W_A = (45)/(634) \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/8xw9ozzlb0rzgdy3gke6n6t5ecpyo36107.png)
![\[ W_B = (45)/(712) \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/bq2iyhiz0v86vrd0lkuylrabrqdrr8xusz.png)
You can then calculate the values:
![\[ W_A \approx 0.0709 \, \text{inches} \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/ofxvf68ogn4yyw3yg90gihdzevrh7tn3zm.png)
![\[ W_B \approx 0.0632 \, \text{inches} \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/9wmv31dwqsqpqfs3681yb5ne1mr3xlrvsy.png)
So, the widths of the two frames are approximately 0.0709 inches for Frame A and 0.0632 inches for Frame B.
