Iwill make you the brainliest easy question show the formula for finding the area of a trapezoid. then find the area of the trapezoid pictured:

153

Step-by-step explanation:

A(Trapezoid)=

Where B and b are the two bases and h is the height.

A(trapezoid)=

A(Trapezoid)=153

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
