Question

If the diagonal and the area of a rectangle are 25 m and 168 m2, what is the length of the rectangle? Select one: a. 12 m b. 21 m c. 24 m d. 17 m

Answer 1

Diagonal of rectangle = 25m
Area of rectangle = 168m2
So,
Another method are-
lw = 168
l^2 + w^2 = 625
(l-w)^2 = 289 so L-w = 17 or w = L - 17
l(l-17) = 168
solving so L= 24 or -7
offcourse Lcannot be (-)ve hence D
I hope you enjoy it.
