If the area of the given trapezoid is 1,188m^2, find the value of x.

VMariaS [17]

Answer: x = 52 m

Step-by-step explanation:

The formula we will use, which solves for the area of a trapezoid, is $a=\frac{a+b}{2} h$ where a is a base, b is a base, and h is the height.

We will input the known values, then solve for <em>x</em>.

$\displaystyle a=\frac{a+b}{2} h$

$\displaystyle 1,188\;\text{m}^2=\frac{36\;\text{m}\;+x}{2}*27\;\text{m}$

$\displaystyle 1,188\;\text{m}^2=(18\;\text{m}+\frac{x}{2})*27\;\text{m}$

$\displaystyle 1,188\;\text{m}^2=486\;\text{m}+\frac{27x}{2}$

$\displaystyle 702\;\text{m}^2=\frac{27x}{2}$

$\displaystyle 1,404\;\text{m}^2=27x$

$\displaystyle x=52\;\text{m}$

If the radius is 18 cm and the angle at centre of circle is 120° then the

PolarNik [594]

The area of a sector is 339.336 cm²

The area of a sector is defined to be as the region of space bounded by a boundary from the center of the circle.

It can be determined by using the formula:

$\mathbf{A = \dfrac{\theta }{360}\times \pi r^2 }$

Given that;

Radius r = 18 cm
Angle θ = 120°

Then. the area of the sector can be calculated as:

$\mathbf{A = \dfrac{120}{360}\times \pi (18)^2 }$

$\mathbf{A = \dfrac{1}{3}\times 3.142 \times 324 }$

A = 339.336 cm²
