Here, I think I can help you out:

1. 21 ÷ 3

= 7

Therefore, the length is 7cm².

2. 35 ÷ 7

= 5cm²

- And so on. Simply divide the area by the length of the side given; you can answer up to question six using this strategy.

7. All sides of a square are the same length.

7 x 7

= 49cm²

9. 2 x 3.5

= 7m²

- The formula to find the area of a square/rectangle is length x width. Just multiply the given lengths for the answers :)

Step-by-step explanation:

Q.1 Solutions

1. Area of rectangle= L×B

21=L×3

21/3=L

7cm Answer

2. Area of square=S×S

35m²=S×7m

35/7=S

5=S

5m Answer

3. Area of rectangle= L×B

5%m²=L×½m

5/½=L

2.5=L

2.5m Answer

4. Area of square= S×S

120mm²=S×10mm

120/10=S

12=S

12mm Answer

5. Area of rectangle= L×B

7%m²=L×1%m

7/1=L

7=L

7m Answer

6. Area of square=S×S

15cm²=S×6cm

15/6=S

2.5=S

2.5cm Answer...

Q.2 Solutions

Note: you might be knowing the formulas so please understand this:

7.49cm

8.400cm

10.86cm

In triangle abc angle a = 40◦, side b = 11 and side c = 5. use the cosine rule to find the length of side a, to two decimal plac
Sonbull [250]
A^2 = b^2 + c^2 - 2bc cos a

    = 11^2 + 5^2 - 2*5*11 cos 40

   =  7.86 to 2 DP's

to find the remaining angles use the sine rule:-
a / sin A = b / sin B so

7.857/ sin 40 =  11 / sin B
sin B = 11 sin40 / 7.857 = 0.8999

<B = 64 degrees 

so <C = 180 - 64-40  =  76 degrees
