Question

A rectangular courtyard 1.12m long and 0.84m wide is to be paved exactly with square tiles ,all of same size. The largest size of the tile which could be used for the purpose is (n×4)cm. Find the value of n​

Answer 1

l = 1.12m

b = 0.84m

Area =  (1.12m )*(0.84m)   =  0.94m²

lets assume length of the square = x

n*x² = 0.94

here n should be whole number so x=0.7cm

Now according to the question,

                             n*4=0.7

                             n=0.7/4

                             n=0.175cm

Hey buddy ❤️❤️

Answer:

❤️❤️

A rectangular courtyard 1.12 m long and 0.84 m wide

1.12 m = 112 cm

0.84m = 84 cm

112 = 2 × 2 × 2 × 2 × 7

84 = 2 × 2 × 3 × 7

HCF = 2 × 2 × 7

Largest size of tile = 2 × 2 × 7 cm

= 4 × 7

=7 × 4

comparing with

n × 4

n = 7

value of n = 7

Hope it helps you ✌️✌️❤️❤️
