Question

Find the value of MN if AB = 3 cm, BC = 2.4 cm, and LM = 4 cm. ABCD ~ LMNO

A: 3.6 cm
B: 3.2 cm
C: 1.8 cm
D: 3.4 cm

Answer 1

its B:3.2

Explanation:

Answer 2

1.8

Explanation:

Since the rectangles are similar, we can find the value of MN using scale factor.

AB/LM = 3/4

The corresponding side of MN is BC:

MN/(2.4) = 3/4

• Cross multiply fractions.

4MN = 7.2

• Divide both sides by 4.

MN = 1.8
