Question

Due tomorrow help me find the perimeter and explain pls!!

Answer 1

x = 7

Explanation:

for rectangle

perimeter (p) = 2(l+b)

having same perimeter both figures have so,

fig 1: fig 2:

2*((2x-5) +3) = 2*(5+x)

2*(2x-2) = 10+2x

4x-4 = 10 +2x

4x-2x = 10+4

2x = 14

x = 7

Answer 2

Explanation:

Perimeter of first one = 2 X ( ( 2x-5 + 3) = 4x - 4

Perimeter of second one = 2 X ( 5 + x ) = 10 + 2x

and these are equal

4x - 4 = 10 + 2x

2x = 14

x=7
