Pls help due soon!!!

Answer 1

Answer:

10m

Step-by-step explanation:

Area of a triangle:  $\frac{1}{2}$bh

where 'b' = base and 'h' = height

plug in known values:  20 = $\frac{4b}{2}$

cross-multiply:  4b = 40

b = 10

Answer 2

Answer:

B) 10 m

Step-by-step explanation:

Area is 20 and Height is 4

Ok so

AREA of a triangle is =1/2Base Times Height

work back

Area=20

Height=4

b=Base

20=1/2b*4

Simplify both sides of the equation.

20=2b

Flip equation

2b=20

Divide both sides by 2

b=10

Base=10 m
