Question

The rectangle below has a total perimeter of 125 cm2.



Write an equation and solve it to find the length of the longer side of the rectangle.

2x + 10 = 125; x = 57.5 cm

x + 5 = 125; x = 120 cm

5x = 125; x = 25 cm

25x = 125; x = 5 cm

Answer 1

hi,
we know that the opposite sides of a rectangle r equal...
so if the length of one long side is "x" then the length of the other long side is too "x"

and the question has given the length of one short side which is 5
hence the opposite sides r equal the length of the other short side is too 5

so the perimeter = 5 + 5 + x + x

which means...
10 + 2x = 125 ----> equation to solve
2x = 125 -10 = 105
x = 105/2 = 57.5 cm

hope this will help ya
