The rectangle has width 8x^8 feet and length 4x^7 feet. Find it’s area as an expression of x.

Question

Simplify answer. Any help would be great.

Answer 1

The area of a rectangle is length times width, so you just multiply them.

For example, if the length was 7x^9 and the width was 9x^6 then the area would be 63x^15.
