The top is a triangle with sides 7 and 5.4 Use the Pythagorean theorem to find the 3rd length.
3rd sides = sqt(7^2 + 5^2( = sqrt(49+25) = sqrt(74)
This side is the base of the lower rectangle.
The dotted line is the hypotenuse of a right triangle.
Use the Pythagorean theorem to solve.
sqrt(10^2 + sqrt(74)^2) = sqrt(174)
The dotted line = sqrt(174)

A computer costs 927 plus VAT where VAT is 20%. We need to find the total cost of the computer.
The total cost = original cost + VAT
Total Cost = 927 + 20% * 927
20% converts to decimal by moving the decimal 2 units up, so it is 0.2
= 927 + 0.2*927
Multiply to find value of tax
= 927 + 185.4
Add to find the total cost
Total cost = 1112.4 euros
