the ratio of length to width of a rectangle is 5:3. If the area of the rectangle is 240m square, find the dimensions of the rectangle.

Question

I need help with this ASAP

Answer 1

Let 3x be the width; then length must be 5x. Area = the product 15x² = 240 sq m.

that means x² = 16 so x =4, thus the dimensions are 12 m by 20 m.
