A right triangle has one leg that measures 7 inches and the hypotenuse measures 12 inches.

kirill [66]

Hypotenuse=H=12in
Perpendicular=P=7in
Base=B=?

Using Pythagorean theorem

$\boxed{\sf B^2=H^2-P^2}$

$\\ \sf \longmapsto \: b = \sqrt{ {h}^{2} - {p}^{2} } \\ \\ \sf \longmapsto \: b = \sqrt{ {12}^{2} - {7}^{2} } \\ \\ \sf \longmapsto \: b = \sqrt{100 - 49} \\ \\ \sf \longmapsto \: b = \sqrt{51} \\ \\ \sf \longmapsto \: b = 7.2in$

What is the area of the trapezoid above?

icang [17]

Answer:

26 square meters (the first option)

Step-by-step explanation:

The area of a trapezoid is (b1+b2)/2*h.

b1=one of the bases (one of the bases that are parallel to each other)

b2= the other base (that is parallel to base 1)

h=height

In this picture, b1=5, b2=8, h=4

So, the area is

(5+8)/2*4

=13/2*4

=6.5*4

= 26 square meters
