Question

Square A is a scaled version of square B. The dimensions of square A are three times the dimensions of square B. The area of square A is 900 sq cm.

Answer 1

The side of square A is 30 cm.

Explanation:

Given that,

The dimensions of square A are three times the dimensions of square B.

The area of square A is 900 sq cm.

Side of square A = 3( side of square B)

Let the side of square B is b. So,

Side of square A, a = 3b

We know that, the area of square is side². So,

`(3b)^2=900\\\\9b^2=900\\\\b^2=100\\\\b=10\ cm`

Side of square A, a = 3(10) = 30 cm

Hence, the side of square A is 30 cm.
