Can someone me with this maths question. asap

Since we are given the perimeter, we add the lengths of the sides and set the sum equal to the perimeter. Then we solve for x.

3x + 3x - 1 + 4x + 1 = 70

10x = 70

x = 7

Now we pick two sides that can be used as a base and a height to calculate the area. In a right triangle, the legs form a right angle, and can be used as base and height.

base = 3x = 3(7) = 21

height = 3x - 1 = 3(7) - 1 = 21 - 1 = 20

area = base * height/2

area = (21)(20)/2 = 21 * 10 = 210

210
