Q.3 Find the missing values:


Answer :

(a) Area of the parallelogram =b × h
Or, b×h =\( 246 cm^2 \)
Or, 20 cm × h =\( 246 cm^2\)
Or, h = \( 246cm^2\) /20 cm = 12.3 cm
(b) Area of the parallelogram =b × h
Or, b×h =\( 246 cm^2 \)
Or, b × 15 cm =\( 154.5 cm^2\)
Or, b = \( 154.5 cm^2\) /15 cm = 10.3 cm
(c) Area of the parallelogram =b × h
Or, b×h =\( 48.72 cm^2 \)
Or, 8.4 cm × h =\( 48.72 cm^2\)
Or, h = \( 48.72cm^2\) /8.4 cm = 5.8 cm
(d) Area of the parallelogram =b × h
Or, b×h =\( 16.38 cm^2 \)
Or, b × 15.6 cm =\( 16.38 cm^2\)
Or, b = \( 16.38 cm^2\) /15.6 cm = 1.05 cm
