Question

How to solve a rectangle length is (8x+5)long and (5x+3)breath find its area

Answer 1

Area of a rectangle = Length * breadth
= (8x+5) ×(5x+3)
= 8x(5x+3) +5 (5x+3)
= 40x2+24x +25x+15
= 40x2 + 49x +15.....(1)
Now find the value of x and substitute in equation (1)
By this we can find the area of rectangle
