Question

Find the area of square whose perimeter is the same as the
perimeter of a rectangle with area 69 cm square and breath
6cm.​

Answer 1

Answer:

perimeter of square=perimeter of rectangle

4×side=2(L+B)

4×side=2×(L+6)

so, first we need to find the length of rectangle=69/6=11.5cm

area of square=

4×side=2×(11.5+6)

4×side=35

side of square=35/4=8.75

area of square=4×8.75=35cm^2
