Q5: B C Q R P S x + 5 A D x ABCD and PQRS are rectangles. Each has an area of 13cm2. AD = x cm and PS = (x + 5) cm Find in terms of x an expression for AB PQ Given that AB = 3cm greater than PQ, form an equation in x and show that it simplifies to 3x2 + 15x 65 = 0 – Solve the equation 3x2 + 15x 65 = 0, giving each answer correct to 2 decimal places. – (i) Show that the perimeter od ABCD is 14.9cm correct to 3 significant figures. Find the difference between the perimeter of two rectangles. Q6: h The length of the base of the parallelogram is 6cm more than its perpendicular height, cm.The area h of this parallelogram is 33.25 cm2. Show that satisfies the equation 4h2 + 24h 133 = 0 h – Solve the equation 4h2 + 24h 133 = 0 – Find the length of the base of the parallelogram.
