Question

. A rectangle has the area equal to that of a square of side 80 cm. If the breadth of the rectangle
is 20 cm, find its length.​

Answer 1

Answer:

Area of rectangle = Area of square

Side of square is 80 cm

so area of square is 6400cm^2

Area of rectangle is 6400cm^2

Breadth of rectangle is 20cm

length of rectangle is 320 cm

Answer 2

Answer:

Side of the square=80cm.

Area of square=(side)².

=(80)².

=6400cm².

Now, Area of rectangle=Area of square=6400cm².

breadth of the rectangle=20cm.

.: Area of rectangle=6400cm².

(l*b) = 6400cm².

(l*20)=6400cm².

l = 6400÷20.

l = 320cm.

Length will be 320cm.
