What’s the area of the triangle?

Area=112
solution: 7 x 4 x 8 = 224
224/2=112
it’s squared btw

ok lets say the number is 375 ok so the five is in the ones place so its worth only 5 the seven is in the tenths place its worth would be 70 and all you had to was multiply the number times 10 because it in the tenths place ok moving on the 3 is in he hundreds place so its worth 300 why because all you have to do is multiply the number in the hundreds by one hundreds
