Question

A square with side 60m and a rectangle with lenght 80m have the same perimeter.find width of the rectangle​

Answer 1

Answer:

40m.

Step-by-step explanation:

The perimeter of the square is 240m, because all 4 sides of a square are equal and 60 x 4 = 240.

Then, the perimeter of a rectangle is (length x 2) + (width x 2) and the perimeter of the rectangle and square are the same so 240 - (80 x 2) = 80

Since 80m is the width x 2, the width of the rectangle is 40m.

Equation: 60 x 4 = 240

80 x 2 = 160

240 - 160 = 80

80 / 2 = 40m

Hope this explanation is good!
