Question

the length and the breadth of a rectangular park are in the ratio 8:5 .A path 1.5 wide runing all around the outside of parakaha an area of 594 sq m find the dimensions of the park

Answer 1

area of rectangle park = 8x * 5x

=40x²

length of outside = 8x + 2 * 2.5 = 8x + 5
breadth of outside = 5x + 2 * 2.5 = 5x + 5

area of out side park = (8x+5)*(5x+5)

=40x² + 65x + 25

area of the park = 40x² - 40x² + 65x + 25

594 = 65x + 25

65x = 594 - 25

Know the answer?

area of rectangle park = 8x * 5x

=40x²

length of outside = 8x + 2 * 2.5 = 8x + 5

breadth of outside = 5x + 2 * 2.5 = 5x + 5

area of out side park = (8x+5)*(5x+5)

=40x² + 65x + 25

area of the park = 40x² - 40x² + 65x + 25

594 = 65x + 25

65x = 594 - 25
