Question

The area of a trampoline is about $1.8\times {10}^4$ square inches.Write this number in standard form. Then represent the area of the trampoline using more-appropriate units.

Answer 1

Step 1: Writing area in standard form.

Given, the area of a trampoline is about $1.8\times {10}^4$ square inches.

$1.8\times {10}^4=18000\mathrm{square}\mathrm{inches}$

Step 2: Representing the area of the trampoline using more-appropriate units i.e. feet.

We know that $1\mathrm{square}\mathrm{feet}=144\mathrm{square}\mathrm{inches}$

Hence, the area of a trampoline in feet $=\frac{18000}{144}$ feet

$=125$ square feet
