Question

Find the missing values.

S. No.	Base	Height	area
(i)	18 cm	5 cm
(ii)	8 m		56 sq. m
(iii)		17 mm	221 sq. m

Answer 1

(i) Given Base 6 = 18 cm; Height h = 5 cm 

Area of the parallelogram = b x h sq. units 

= 18 x 5 cm² 

= 90 cm²

(ii) Base b = 8m; Area of the parallelogram = 56 sq. m 

b x h = 56 

8 x A = 56 

h = \(\frac{56}{8}\)

h = 7 m

(iii) Given Height h = 17 mm 

Area of the parallelogram = 221 sq. mm 

b x h = 221 

b x 17 = 221 

b = \(\frac{221}{17}\)

b = 13 m 

Tabulating the results, we get

S. No.	Base	Height	Area
(i)	18 cm	5 cm
(ii)	8 m		56 sq. m
(iii)		17 mm	221 sq. m
