A) Area of triangle =  $\frac{1}{2}$12  ×10cm×24cm = 120 $cm^2$cm2 

B) 2 triangles form a rectangle with length 24cm and breadth 10cm

100÷24 = 4 R4 

60÷10 =6

Number of rectangles that can be cut = 4 ×6 =24

Number of triangles that can be cut = 24×2= 48

4A = D so A =  $\frac{D}{4}$D4  

B = 2C 

B = D + 42

So C = $\frac{D+42}{2}$D+422  

Also for parallelogram, A + B = C + D

So: 

$\frac{D}{4}$D4  + (D + 42) =  $\frac{D+42}{2}$D+422  + D

D + 4D + 168 = 2D + 84 + 4D

D = 84

So:

A =  $\frac{84}{4}$844  = 21

B = 84 + 42 = 126

C = 126 ÷ 2 = 63

Ans (a):

Area of Parellelogram = A + B + C + D = 21 + 126 + 63 + 84 = 294 cm$^2$2  

Ans (b):

C - A = 63 - 21 = 42cm$^2$2

  $\frac{2}{10}$210  $\frac{3}{5}$35  

=  $\frac{2}{10}$210  + $\frac{6}{10}$610  

=  $\frac{8}{10}$810  

$\frac{4}{5}$45

$9.50 

Duration is : 2 hour 15 minutes 

First one hour :$5

Remaining 1 hour 15 mins will be part of additional and part thereof so $1.50×3 = $4.50 

Total amount is $5+$$4.50=$9.50

S |___________|        3457

T |_________|            (3457-34) = 3423

M |_____________|    (3423 + 145) = 3568

Ans: 3457 + 3423 + 3568 = 10448

All         |_____________________| 419 toys

Jayden  |__| 50 toys

Jame     |____| 1U toys

Eheh     |____|____| 2U toys

Jayden + Jame + Eheh = 419

50 + 1U + 2U = 419

3U = 369

U = 369 ÷ 3 = 123 

Ans: So Jame have 123 toys

Ans =  $\frac{3}{2}$32  +  $\frac{2}{5}$25  =  $\frac{15}{10}$1510  +  $\frac{4}{10}$410  =  $\frac{19}{10}$1910  = 1 $\frac{9}{10}$910

Total triangles = 16

 $\frac{3}{8}$38  of 16 is 6 traingles

Ans = 6 - 5 triangles = 1 more traingle to be shaded
