Question

the perimeter of the rectangle below is 90 units. find the length of side PS. write your answer without variables.

Answer 1

the answer is

the length of side vy is (2y+3)-----> 19.4 units

Explanation:

perimeter of a rectangle=2*[base+height]

base=3y+1

height=2y+3

perimeter=90 units

so

90=2*[(3y+1)+(2y+3)]-----> 90=2*[5y+4]----> 10y+8=90----> y=8.2 units

base=3y+1-----> base=3*8.2+1-----> 25.6 units

height=2y+3----> height= 2*8.2+3---> 19.4 units
