Question

the area of rectangle is 1936 square meter. If the length of the rectangle is 4 times its breath .Find the dimension of the rectangle.

Answer 1

Length (l) = 4 breadth (b) ------ 1
Area of rectangle = length × breadth ------- 2
so substitute l = 4b in equation 2
4b × b = 1936
4b^2 = 1936
b^2= 1936/4
b=√484
b=22
