Question

Please help me with 15 & 16. Step by Step!!!!

15. The length of a rectangle is four times its width. If its width is x^5 units, what is the area of the rectangle?

16. The width of a rectangular prism is six times its length. The height is five times its length. If its length is m units, what is the volume of the prism?​

Answer 1

15. 4x¹⁰

16. 30m³

Explanation:

15. Area of Rectangle is given by A=LW

since W=x⁵ and L is 4 times W, L=4x⁵

therefore, A = x⁵(4x⁵) = 4x¹⁰

16. Volume of Rectangular Prism is V=LWH

W=6L=6m and H=5L=5m and L=m

so V = m(6m)(5m) = 30m³
