Question

Carter is building a model sailboat. The boat will have two triangular sails. One sail will have a base of 24 inches and a height of 56 inches. The other sail will have a base of 14 inches and a height of 33 inches. What is the minimum amount of material Carter needs to build the sails? 1,806 inches2 1,344 inches2 903 inches2 672 inches2

Answer 1

Find the area of each triangle and then add them together.

The formula for area of a triangle is $\frac{1}{2} \times base \times height$.

Area 1 = $\frac{1}{2} \times 24 \times 56$ = 672 square inches.

Area 2 = $\frac{1}{2} \times 14 \times 33$ = 231 square inches.

Total area = $672 + 231 =$ $\bold{903}$ $\bold{\: square\: inches}.$

Answer 2

the areas of the sails:-

1. (24*56 )/2= 672

2. (14*33)/2 = 231

total = 903 inch^2.
