Question

I really need help with math i am not the best at it

Answer 1

a Given:-

A image.

To find the total area of the given image.

So the given image is splitted into three images they are a triangle at the top and a rectangle at the middle and parallelogram at the bottom.

So the formula for triangle is,

$A=\frac{1}{2}\times b\times h$

So the formula for rectangle is,

$A=l\times b$

So the formula for parallogram is,

$A=b\times h$

So from the given image we have the values as,

Triangle has,

$b=3,h=4$

Rectangle has,

$l=10,b=3$

Paralleogram has,

$b=5,h=2$

So now we substitute the following values. so we get,

For Triangle,

$\begin{gathered} A=\frac{1}{2}\times3\times4 \\ A=3\times2 \\ A=6 \end{gathered}$

For Rectangle,

$\begin{gathered} A=10\times3 \\ A=30 \end{gathered}$

For paralleogram,

$\begin{gathered} A=5\times2 \\ A=10 \end{gathered}$

So the total area is,

$\begin{gathered} A=6+30+10 \\ A=46 \end{gathered}$

So the total area is 46 in.sq.
