Question

the length of a rectangle is 16 cm and its perimeter of a square with side 12.5 cm . find the area of the rectangle

Answer 1

Answer:

144 sq.cm

Step-by-step explanation:

length of rectangle=16cm

length of side of square=12.5cm

perimeter of square=4*side =4*12.5=50cm

perimeter of rectangle = 2(l+b)

2(l+b) = 50

2(16+b) = 50

32+2*b=50

2b = 50-32

b = 18/2

b = 9cm

so,area of rectangle = l*b = 16*9 = 144sq.cm
