Question

Use either the square of a binomial or the

difference of two squares to find the area of
each rectangle.​

Answer 1

9. 2916 sq. cm

10. 864 sq. in

Explanation:

9.) 54 cm * 54 cm = area of square

(50 + 4)*(50 + 4) = 50*50 + 8*50 + 16

= 2500 + 400 + 16 = 2916 sq cm.

10. 24 in * 36 in. = area of rectangle

get: (30 - 6)*(30 + 6) = 30^2- 6^2

= 900 - 36 = 864 sq. in.
