The formula of an area of a trapezoid:

A=\dfrac{base_1+base_2}{2}\cdot height

We have

base_1=25\ cm\\\\base_2=19\ cm\\\\height=20\ cm

Substitute:

A=\dfrac{25+19}{2}\cdot20=\dfrac{44}{2}\cdot20=22\cdot20=440\ cm^2

A triangle has sides with lengths of 60 feet, 63 feet, and 87 feet. Is it a right triangle?
Sedaia [141]

Answer:

Yes

Step-by-step explanation:

We can use the Pythagorean Theorem to check if this triangle is a right triangle:

a^2+b^2=c^2

Note that a and b are the legs of the triangle and c is the hypotenuse:

Substitute the lengths of the sides into the equation:

60^2+63^2=87^2

3600+3969=7569\\7569=7569

Therefore this triangle is a right triangle.
