Question

what is the area of the triangle?
(an image of a right triangle with height 0.9 ft, base 0.4 ft, and hypotenuse 1 ft)
blank square feet

Explanation:

Step1: Recall triangle area formula

The area of a right triangle is $\frac{1}{2} \times \text{base} \times \text{height}$

Step2: Substitute given values

Base = $0.4$ ft, Height = $0.9$ ft
Expression: $\frac{1}{2} \times 0.4 \times 0.9$

Step3: Calculate the product

First compute $0.4 \times 0.9 = 0.36$, then multiply by $\frac{1}{2}$
Expression: $\frac{1}{2} \times 0.36 = 0.18$

Answer:

0.18 square foot
