Question

a square Side 2 centimetre is joined with a rectangle of length 15 cm and breadth 10 cm find the perimeter of the combinated shape​

Answer 1

48cm is the answer just join the figures and add all the lengths of the boundaries visible

Answer 2

It is given that a square of side (a) 2 cm is joined with a rectangle of length (l) 15 cm and breadth (b) 10 cm.

So, we know that perimeter is the length of the boundary of a closed figure.

So, to get the perimeter here, we have to add all the sides (their length).

Let he perimeter be 'P' then.

ATQ:-

=>(a+a+a)+(l+l)+b=P

=>3a+2l+b=P

=>3×2+2×15+10=P

=>6+30+10=P

=>46 cm=P

So, the perimeter of the new figure formed=46 cm
