Q1) Find the areas of the rectangles whose sides are:

(a) 3 cm and 4 cm

(b) 12 m and 21 m

(c) 2 km and 3 km

(d) 2 m and 70 cm



(a) Area of rectangle = length x breadth

= 3 cm x 4 cm = 12 cm.sq

(b) Area of rectangle = length x breadth

= 12 m x 21 m = 252 m.sq

(c) Area of rectangle = length x breadth

= 2 km x 3 km = 6 km.sq

(d) Area of rectangle = length x breadth

= 2 m x 70 cm = 2 m x 0.7 m = 1.4 m.sq

"Hello Guys completed homework today wedding, but number one which is find the areas of the following rectangle first for the formula for the area of a rectangle is length into breadth. So you just need to multiply the sides to get the answer.

Next one is 2 kilometer in three kilometers under its meters by 2 meters where next one is too gloomy 20 kilometers will be 2 into 3, which will be equal to 6 kilometer Square. Next one is 2 and 70. So please note that although both the units are different here. It's Vita erat centimeter will make the centimeter into meter. There is becomes 2 into 2 into 0 .7 because I'm converting centimeter meter, which will be equal to one point four meter Square. Thank you so much guys for watching the video.
