Question

The area of a parallelogram is 19 1/2 cm^2 .If it's height is 1 6/7 cm . find it's base .
explain it clearly ​

Answer 1

Answer:

10.5 cm

Step-by-step explanation:

We know that,

Area of Parallelogram = Base x Height

now,

Area of Parallelogram = $19\frac{1}{2}$ = $\frac{39}{2}$ $cm^{2}$

Height = $1\frac{6}{7}$ = $\frac{13}{7}$ $cm$

Let Base = $b$

Therefore, by area formulae,

Area = Base x Height

Base = $\frac{Area}{Height}$  = $\frac{\frac{39}{2}}{\frac{13}{7}}$  = $\frac{39*7}{2*13}$ = $\frac{21}{2}$ = 10.5 cm

Hope This Helps!
