Question

literally help meee because I don't understand ​

Answer 1

It is very simple

Firstly you should draw a line from end of the 7cm line perpendicular to the 11cm line

Then you will get a rectangle and a triangle find the area and add them

Area of rectangle will be
(l*b)
=3*7
=21

Then find the area of the triangle like
(1/2)b*h
=(1/2)3*4
=6
The simply add the areas and you can get the answer as 27

Hope it helps : )

Answer 2

Answer and Step-by-step explanation:

You are being asked to find the area of a trapezoid. The area of a trapezoid is:

$\frac{a+b}{2}$ × h

Where:

a = Top base

b = Bottom base

h = Height

Plug in the values given to you via from the page.

$\frac{7+11}{2} (3)\\\\\\\frac{18}{2}(3)\\\\(9)(3) = 27$

The answer (the area) is 27 $cm^2$.
