I solved the 2nd q so dont need to help..... just help me with the 1st q

Tks in advance!!!! :)

Because the length of the rectangle is 12 m and the rectangle can fit 3 squares nicely, the sides of each square
= 12/3
= 4 m

So each square is 4 m by 4 m and the rectangle is 12 m by 4 m (this breadth of the rectangle must be 4 m because we must fit one square along the breadth).

Total area is that of 2 squares and 1 rectangle
= 2 x 4 x 4 + 12 x 4
= 32 + 48
= 80 m2

Can you pls put that in the answer section so that I can give you upvotes

Currently do not have access to writing materials, so it’s alright

I also need you to do that because I have another question to post

Many thanks

For Q19, because the area of the square is 81 cm2, the sides of each square must be 9 cm.

(I am not sure if you have learnt the square root yet; if you have not, we find two same numbers which multiply to 81, and this is 9 x 9)

Then, the breadth of each rectangle
= 12 - 9
= 3 cm (you can see this using two of the joined rectangles)

From here, there are two ways to do this question.

Total area of the 4 rectangles
= 4 x 12 x 3
= 4 x 36
= 144 cm2

Or,

Length of giant square (yes, it’s a square)
= 12 + 3
= 15 cm

Total area of giant square
= 15 x 15
= 225 cm2

Total area of the 4 rectangles
= Area of giant square - Area of small square
= 225 - 81
= 144 cm2

Tks!!!!!
