KS2 Primary Maths Age 13-17 - Arithmetic - Problem: - Explained

Angela has tiles of the same size. She uses four tiles to make a length of 76 cm and adds one more tile. To find the total length of five tiles, the length of one tile is calculated by dividing 76 by 4, resulting in 19 cm per tile. Adding the fifth tile, the total length is 95 cm. The problem awards two marks: one for the final answer and one for calculating the length of one tile.
