Question

5. Find the areas of the squares whose sides are:
(1) 8 cm
(ii) 14 m
(iii) 2 m 50 cm​

Answer 1

Answer:

(1) 64cm square

(2)196m square

(3)4 square metre

Answer 2

Answer:

1) 64cm²

2) 196m²

3) 6.25m²

Step-by-step explanation:

1) Area of square= side²

Area of square=8²m=8×8m

=64cm²

2) Area of square=side²

=14²m=14×14m

=196m²

3) firstly, we will convert 2m 50cm into metres.

we know,

1m=100cm

& 1cm=1/100m

*(for converting into metres first convert 2m 50cm into cm)

1m=100cm

2m 50cm= {(2×100)+50} cm

= 200+50 cm

=250 cm.

now,

1cm=1/100m

250cm=250/100 m

=25/10 m( 0 gets cancelled)

= 2.5m.

Now,

area of square= side²

= 2.5²m= 2.5×2.5 m

=6.2500m²/6.25m²
