Question

The perimeter of a rectangular garden is 710ft. The two long sides of a garden are each 310 ft long. You are asked to find the length of the other sides. Which equation models this situation.

Answer 1

P=710ft
Side AB=310 ft
Side DC=310 ft
Side AD=side BC
P of rectangle is AB+DC+AD+BC
710=310+310+2AD
710=620+2AD
710-620=620+2AD-620
90=2AD
90/2=2AD/2
45=AD
Both sides are parallel so they are same
So other 2 sides are 45ft each.
