3. Length: measured in units (1 – dimension) Area: measured in ________ units (2- dimensions) If 2 figures are , then they have the ________ area. square same

4. FORMULAS SquareRectangle A = _____ P = _____P = __________ s 4s w l lw 2l + 2w or bh b h

5. Ex. 1Ex. 2 A = _____A = 36 ft 2P = _____ P = 4s P = 4(5) P = 20 m20 m s = 6 ft P = 4s P = 4(6) P = 24 ft 24 ft

6. Ex. 3Ex. 4 A = _____ P = ____A = 24 cm 2 P = ____ A = lw A = 7(3) P = 2l + 2w P = 2(7) + 2(3) P = 20 in 20 in A = lw 24 = l(4) l = 6 cm 6 cm P = 2l + 2w P = 2(6) + 2(4) P = 20 cm 20 cm

7. Ex. 5A = _____ 2 2 3 3 A = lw A = 6(5) A = lw A = 3(2)

8. Ex. 6A = _____ 2 3 A = lw A = 2(4) A = lw A = 6(3) 6

9. Ex. 7A = _____ x = 8 A = lw A = 8(6) x = 8

10. Ex. 8A = _____ sl 30° ll hyp hyp = 2 sl hyp = 2 (3) Do we need to find this? A = lw hyp = 6
