Question

A rectangle has perimeter 86 cm and length 37 cm. what is its width

Answer 1

The rectangle's width is 6.

Explanation:

You are given the perimeter is 86 cm. The perimeter is the sum of all the sums. For a rectangle, use the formula, P = 2l + 2w. So, we plug the given into our equation: P = 86, l = 37. This results in:

86 = 2(37) + 2w

86 = 74 + 2w

Subtract 74 on each side.

2w = 12

Then, divide each side by 2.

w = 6

Hopefully this helped. And good luck in your studies.

Answer 2

6 cm

Explanation:

1. 37 × 2 = 74 cm
2. 86 - 74 = 12 cm
3. 12 ÷ 2 = 6 cm
4. So, the width is 6 cm

I hope this helps!
