EXERCISE 5.3 1. If the perimeter of a square is given by P = 4s and a side is represented by s, determine Pifs=1234 m 2. If the perimeter of a rectangle is given by P=2(1+b) and the length is represented by land the breadth is represented by b, determine Pif/=12 cm and b= 7,3 cm. 3. If the area of a circle is given by A = r², determine the area of a circle with a radius (r) of 4 cm if it is 3,14. 4. If distance covered (d) covered is represented by the formula d=sxt where s represents speed and t represents time, determine the distance covered in 3 hours at a constant speed of 120 km/h. 5. If the area of a triangle is given by A=xbxh, determine the area if b = 5 cm and h = 12 cm. P
