Question

the area of a square is 6400m2 find the area of a rectangle whose breadth is the same as that of the square and length is 20 m more than its breadth.

Answer 1

Step-by-step explanation:

one side of the square = √6400

= 80 m = breadth of the rectangle

length of the rectangle = 80+20 = 100 m

area of the rectangle = 100 x 80

= 8000 m2
