Answer:
42.12cm²
Step-by-step explanation:
Firs well have to find the hypotenuse of the big and small right angled triangles because it is the length of the long and short diagonals which is needed in solving
The bigger triangle
Using Pythagoras theorem
let the length be x
x²=10²+6²
x²=100+36
x²=136
√x²=√136
x=√136
x=11.7m
The smaller triangle
Using Pythagoras theorem
let the length be y
y²=6²+4²
y²=36+16
y²=52
√y²=√52
y=√52
y=7.2
Now to find the total area of the shape which is a kite
Formula=
1/2 x D1 x D2
D1 is the long diagonal which is the hypotenuse of the bigger triangle and D2 is the shorter diagonal the hypotenuse of the smaller triangle
