area of triangle + area of the rectangle1 and 2
using Pythagoras theorem
hypotenuse square is equal to base square + height square
7 square is equal to 2 square + height square
height is equal to root over 7 square + 12square
height = root 53
height =3root 7
area of triangle is equal to half base into height area of triangle is equal to half into 2 into 3 root 7
a triangle is equal to 3 root 7 cm square
area of rectangle is equal to length into breadth which is equal to 4 into 21
area of right triangle is equal to 84 centimetre square
area of rectangle 2 is equal to length into breadth
which is equal to 2.1 cm into 8 cm which is equal to 16.8 CM square
adding the area of the rectangle and triangle is equal to the area of candle 3 root 7 + 84 + 8 cm square is equal to area of candle 3 root 7 + 96 CM square
area of 25 candle is equal to 3 root 7 + 96 CM square
area of 25 candles is equal to 75 root 7 plus 5400 CM square
I know there is a calculation mistake but the method is correct you can use this method to solve these kinds of questions hope this might help you
