A Trapeziod Has An Area Of 42 M^2 And Altitude Of 2m. Its Two Bases Have The Ratio 2:4. How Long Is The Shorter Base

A trapeziod has an area of 42 m^2 and altitude of 2m. Its two bases have the ratio 2:4. How long is the shorter base

Answer:

14 cm.

Explanation:

Area of trapezoid=

$a \times \frac{b1 + b2}{2}$

where:

a=altitude

b1,b2=bases

Insert the given above in the formula. We have,

$42 = \frac{2x + 4x}{2} \times 2$

42=6x

x=7.

So, the shorter base 2x is 2(7)=14.
