What is the length of the base of a right triangle with an area of 20 m² and a height of 4 m? 5 m 10 m 80 m 160 m
The length of the base of a right triangle is 10 m because the area formula for a triangle is BxH/2 (B=Base H=Height) (/2= divide by 2)
so plugging it in 4m x 10m = 40m
40m/2 = 20m
Answer:
B. Length of the base is 10 m.
Step-by-step explanation:
We are given a triangle having,
Area = 20 m²
Height = 4 m
Since, we know that,
Area of a triangle = \(\frac{1}{2}\times Base\times Height\)
i.e. \(20=\frac{1}{2}\times Base\times 4\)
i.e. \(20=2\times Base\)
i.e. \(Base=\frac{20}{2}\)
i.e. Base = 10 m.
Hence, the length of the base is 10 m.
