Question

the sides of a rectangular plot are in the ratio 5:4 and its area is equal to 500 sq m. find the perimeter of the plot
​

Answer 1

let length and width of the rectangular plot is l and w;

l:w = 5:4;

we can write it as l = 5w/4;

Area of rectangular plot = length*width;

500 = l*w;

500 = (5w*w)/4;

2000 = 5w2;

w2 = 2000/5;

w2 = 400;

w = 20; and l = 5*20/4 = 25;

Perimeter of rectangular = 2(l+w);

Perimeter = 2(25+20);

perimeter = 90m

Answer 2

Answer:

perimeter 90 m
