PSLE The perimeter of figure TUVWX is (4
g + 17) cm. The perimeter of square TUVW is 8 cm.
- Find the perimeter of triangle TWX in terms of g.
- The perimeter of figure TUVWX is 37 cm. What is the value of g? Give your answer in cm.
(a)
Length of the square
= 8 ÷ 4
= 2 cm
Total lengths of TU, UV and VW
= 3 x 2
= 6 cm
Perimeter of triangle TWX
= 4
g + 17 - 2 - 2
= (4
g + 13) cm
(b)
4
g + 17 = 37
4
g = 37 - 17
4
g = 20
g = 20 ÷ 4 = 5
Value of
g = 5 cm
Answer(s): (a) (4
g + 13) cm; (b) 5 cm
