Vivaan is building a fence around the edge of his garden, shown below. The material for the fence costs £3 per metre.

How much will his fence cost?

• £32

•  £69

•  £196

•  £9.6

•  £96

Answer explanation

Start by finding the missing lengths. The missing length on the left is equal to 4 + 5 = 9 m. The other missing length is equal to 7 − 4 = 3 m. So the perimeter of the garden is 4 + 4 + 3 + 5 + 7 + 9 = 32 m. The fence will be 32 m long, so it will cost 32 × £3 = £96.
