Triangle swv is an isosceles triangle,
Thus if MW is drawn perpendicular to the base SV of the triangle,
M will be the midpoint of SV.

Therefore triangle SWT and VWU have the same height.
Since the base are the same too, area of triangle VWU = 30 cm^2

Area of triangle XWU = 30/5 x 3 = 18 cm^2.
Area if triangle TWU = 30 +30 -45 = 15cm^2.
Therefore shaded area = 15 +18 = 33

Sorry for asking a blur question but why is area of triangle TWU =30+30 -45? Thanks in advance.

Thanks so much for the answer piggylala. sorry for the repost. super blur.

For (a), is the answer 100 or 160? Can somebody confirm it for me. Thx.

Distance travelled by van to meeting point is 410/2 -30 = 175 km
Distance travelled by van in 1 and half hour 50 x 1.5 = 75 km
Distance more to travel from 1 and half hour point to meeting point is 175 - 75 = 100km

My son is in P5 Maris Stella and I did not get any circular

Had the Maths workshop already where the teachers teach the parents how to answer the maths questions.
