Answer:

414cm^2

Step-by-step explanation:

Given data

Base a= 9cm

Hence the expression for the surface area is

SA=2a^2+4ah

A=2*9^2+4*9*7

A=162+252

A=414cm^2

Hence the surface area is 414cm^2

Create an equation for this and solve for h, how many hours Gina can rent the surfboard for $90.

Your equation should look like:

5h + 20 = 90

Subtract 20 from both sides.

5h = 70

Divide both sides by 5.

h = 14

Gina can rent a surfboard for 14 hours if she has $90.
