Answer:
the area is 5.25 and the perimeter is 14
Step-by-step explanation:
first multiply 6cm and 1 3/4 which converts to 1.75, so 6x1.75+10.5 and to find the area of a triangle you multiply the base by the height and divide by 2 so 10.5 divided by 2 is 5.25 for the area, the perimeter is 14 because you're supposed to add all the sides and the sum is the perimeter 20 6 and 1/4 is converted to 6.25 therefore you add 6.25,6, 1.75 together to get 14
