Question

The perimeter of a rectangle is equal to that of a square with side of 18m. If the rectangle is 17m wide, find its length.




Explain with full explanation ​

Answer 1

Step-by-step explanation:

b = 14m. a = 18m

l (length)= ?

Perimeter of rectangle = Perimeter of square

2(l+b) = 4a

2(l+17) = 4(18)

2l + 34 = 72

2l = 72 - 34

2l = 38

l = 38/2

l = 19

length = 19m
