Find the area, in square feet, of a triangle whose base is 42⁄3 feet and whose altitude is 84⁄7 feet. A. 135⁄21 B. 20 C. 40 D. 2
CaHeK987 [17]

Answer:

Option B. 20\ ft^{2}

Step-by-step explanation:

we know that

The area of a triangle is equal to

A=\frac{1}{2}bh

we have

b=4\frac{2}{3}\ ft

h=8\frac{4}{7}\ ft

Convert mixed numbers to an improper fractions

b=4\frac{2}{3}\ ft=\frac{4*3+2}{3}=\frac{14}{3}\ ft

h=8\frac{4}{7}\ ft=\frac{8*7+4}{7}=\frac{60}{7}\ ft

substitute the values

A=\frac{1}{2}(\frac{14}{3})(\frac{60}{7})\\ \\A=\frac{14*60}{2*3*7}\\ \\A=\frac{840}{42} \\ \\A=20\ ft^{2}

5 ÷ x for x = 1/3 solve
WARRIOR [948]
So if x is equal to 1/3, then our equation would be 5/(1/3). When dividing by a fraction, you can multiply by the reciprocal to find the answer, meaning that if you divide by 1/3, you can multiply by 3/1. So your answer would be 15.
5/(1/3)=x
5*3=x
15=x
