What is the area of this

A = 54 um²

Hi there !

we have 3 triangles and a rectangle

A = A₁ + A₂ + A₃ + A₄

A(triangle) = bₓh/2

b = base ; h = height

A(rectangle) = l ₓ w

l =  length ; w = width

= (3ₓ2)/2 + (6ₓ1)/2 + (6ₓ2)/2 + (7ₓ6)

= 6/2 + 6/2 + 12/2 + 42

= 3 + 3 + 6 + 42

= 54 um²

Good luck !

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

she will most likely have 33
