Question

A square and a rectangle have the same perimeter. The square has a side length of 8x units. The rectangle has a length of (4x + 10) units and a width of 14 units. What will be the perimeter of both the rectangle and square?

A. 34 units
B. 60 units
C. 64 units
D. 2 units

Answer 1

the answer is d(2 units)

Answer 2

C 64 units

Explanation:

P = 2L + 2W

square

2(8x) + 2(8x) = 16x + 16x = 32x.

rectangle

2(4x + 10) + 2(14) = 8x + 20 + 28= 8x + 48

32x = 8x + 48

-8x -8x

24x = 48

divide both sides by 24

x = 2

P = 32(2) = 64
