Chapter 9: Q. 312 (page 1078)

A square garden will be made with a stone border on one edge. If only (3+10) feet of stone are available, simplify(3+10)2 to determine the area of the largest such garden. Round your answer to the nearest tenth of a foot.

Short Answer

Expert verified

The area of the largest garden is 38.0 square feet.

Step by step solution

01

Step 1. Given information.

Lenght of the stone is (3+10)feet.

Area of the largest garden is (3+10)2.

02

Step 2. Determine the area of the garden to the nearest tenth.

On simplifying the given expression, we get

(3+10)2=(3)2+2(3)(10)+(10)2=9+610+10=(9+10)+610=19+610

Round your answer to the nearest tenth.

19+610鈮�19+6(3.16)=19+18.96=37.96鈮�38.0

03

Step 3. Conclusion.

The area of the largest garden is 38.0 square feet.
