Question

Necesito ayuda en una tarea de matemáticas pero es muy difícil si me pueden ayudar se lo agradezco. Es muy larga lo que dice es the area of the triangle above will be equal one half of a rectangle that is 5 units long _ units wide.( input only while numbers, such as 8.)

Answer 1

step 1

Find out the area of the triangle

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

where

b=5 units

h=4 units

substitute

$\begin{gathered} A=\frac{1}{2}*5*4 \\ A=10\text{ units}^2 \end{gathered}$

step 2

The formula to calculate the area of a rectangle is given by

$A=L*W$

where

Remember that the area of the triangle is on half of the rectangle

area of the triangle is 10 square units

that means

The area of the rectangle is 20 square units

so

we have

A=20 unit2

L=5 units

W=?

substitute in the formula

20=(5)*(W)

solve for w

w=20/5

w=4 units
