Question

Please help asp please

Answer 1

76

Explanation:

Hello There!

The area can be found by using this formula

`A=(a+b)/(2) h`

where a and b = bases and h = height

we need to find the height before we can find the area

the shape was split into a triangle and a square

because its a square and one of the side lengths is equal to 8cm the height will be equal to 8cm

now we plug in the known information into the formula

`A=(11+8)/(2) 8\\11+8=19\\(19)/(2) =8.5\\8.5*8=76\\A=76`

so we can conclude that the area of the trapezoid is 76 square centimeters

Answer 2

C) 76 cm²

Explanation:

area = (8 x 8 ) + (3 x 8 x 0.5) = 76 cm²

another way is:

area = 1/2(b1 + b2)(h)

area = 1/2(11 + 8)(8) = 76 cm²
