Perimeter: 4x + 2

The perimeter is equal to 2 times the length plus 2 times the width.

2(x + 1) + 2(x)

2x + 2 + 2x

4x + 2

Area: x^2 + x

The area is equal to the length times the width.

(x + 1)(x)

x^2 + x

Option A because the whole triangle equals 180 degrees so as long as your option plus the numbers in the triangle equal 180° you will get it right

Solve for the area:<br><br><br><br> 32 cm^2<br> 16 cm<br> 32 cm<br> 16 cm^2

MA_775_DIABLO [31]

<h3>Given : </h3>

Base of triangle = 8 cm
Height of triangle = 4 cm

$\\$

Area of triangle = ?

$\\$

<h3>Solution :</h3>

As, we have :

Base of triangle, b = 8 cm
Height of triangle, h = 4 cm

$\\$

So, to find area of triangle we have a formula :

$\large \underline{\boxed{\bf{Area_{(triangle)} = \dfrac{1}{2} \times b \times h}}}$

$\tt : \implies Area = \dfrac{1}{2} \times 8 \: cm \times 4 \: cm$

$\tt : \implies Area = \dfrac{1}{2} \times 32 \: cm^2$

$\tt : \implies Area = \cancel{\dfrac{32}{2}} \: cm^2$

$\tt : \implies Area = 16 \: cm^2$

$\\$

Hence, area of given triangle is 16 cm².
