Can yu see the picture please I hope you can.
No we cant
Here is the picture it worked yeah I am so so so so so so so so so happy
The picture is in moderation I am so so so so so HAPPY!!!!!!!
Hey.....good pic, Nickolas !!!!
The surface area of the three squares = 3(2)^2 = 12 units^2
We have two equilateral triangles with area of 1.5....so...their total surface area = 2(1.5) = 3 units^2
So...total surface area = 12 + 3 = 15 units^2
Thankyou so much!!!
You's are awsome
Well...... I try to give good answers !!!!
Thanks any how
